ver:10 a ) what kind do I need to get I want to upgrade to 512 ram . 
thank you paul black

Dear badboy45,

The "845 G Max MS-6580" mainboard, manufactured by MSI using the Intel
845 G Chipset, needs the following kind of RAM:

184-pin DDR DIMM RAM

RAM units from 64MB to 512MB are supported by the device. In case your
mainboard is already equipped with one 256MB RAM unit, with two of the
three RAM slots still unoccupied, the easiest way of upgrading your
computer to 512MB RAM would be to buy any additional 256MB 184-pin DDR
DIMM RAM unit.

Should you need additional technical information, please have a look
at this MSI product support website with the downloadable manuals for
the 845 G Max MS-6580:
